The combination shown in Fig. 6 com prises again two reels C and D The web 0 issuing from the reel 0 traverses successively the sets 0, A and B and receives the impression in three colors on both sides. The web (Z issuing from the reel D only traverses the set D and consequently receives the impression in one color only on its two sides.

In the combinations shown in Figs. 1, 2, 3 and 5 the tape beds or supports X which are usually stretched horizontally between the sets A and B on one side and C, and D, on the other are retained and serve, in case of the breakage of the web passing between the upper printing rolls C and D, to prevent the loose ends from falling into and fouling the lower rolls A and B.

In the combinations shown in Figs. 4 and 6 the tape beds are suppressed since one of the paper webs crosses the usual position of the beds.

It is plain that for printing a newspaper the use of one or other of the combinations proposed effects the color printing on different pages for each combination.

It is obviously also possible to use either the combination of Fig. 5 or that of Fig. 6 both of which allow the printing of 8 full size pages four of which are in one color and four in three colors.

In point of fact in the case of Fig. 5 the pages printed in one color are pages 3, 4, 5 an 6, and those printed in three colors are pages 1, 2, 7 and 8 while in the case of Fig. 6 it is the pages 1, 2, 7 and 8 which are printed in one color and the pages 3, 4, 5 and 6 which are in three colors.

It is known that in ordinary machines of the Duplex-Tubular type two stereotype plates are mounted on each cylinder 6. One of the plates h abuts against a collar 6 (Figs. 7, 8 and 9) with a chamfered edge carrying with it by means of bent metal wires 2' the dogs 71 which ride up inclined planes and which are applied to the edge of the plate It on the side opposite to the ring or collar 6 The second plate It is held between the dogs 2' on one side and the dogs i on the other side.

To allow of the transverse regulation of the plates with reference to the paper web according to our invention we have made the two portions 6 of the ring 6 movable. Each part or clamp 6 (see particularly Fig. 9) is furnished with a screw threaded hole in which engages a screw a rotatably movable, but held at its two ends. On turning the screw a in one direction or the other the clamps e are moved and in consequence the position of the plates on the surface of the cylinders is modified.

Fig. 10 shows one of the adjusting devices F used for the longitudinal regulation of the paper web with reference to the stereotype plates. 7 is a roller mounted in a fixed position on a trunnion in the frame F. f is a roller mounted on trunnions in the ends of two arms i fast with the axis of the roller 7. The axis of the roller 7, also carries an arm f at the extremity of which is pivoted a screw nut f in which screws a threaded member f. The threaded member f" is provided with a hand wheel f and two collars situated one on either side of a socket f pivoted on the frame F. When the hand wheel f" is turned the position of the roller f is altered, which alteration changes the length of the path of the paper web a. The arms i can be set on the axis of the roller 7 inclined at some angle to the arm f. The turning rollers G are of the usual type.

It is very evident that the invention is not limited to the combinations which have just been described. Furthermore the arrangements according to the invention are applicable to every Duplex Tubular or analogous rotary machine with multiple sets, whatever he the number of sets.

What we claim and desire to secure by Letters Patent of the United States is 1. In a rotary printing press, a web take-up device comprising a stationary guide roll over which the web passes, an adjustable take-up roll pivoted on the axis of the stationary roll, and manually operated means for swinging the take-up roll on its axis to regulate the length of the path of travel of the web.

2. In a rotary printing press, a web takeup device comprlsing a fixed guide roll, a pair of levers fast with the axis of the guide roll, a take-up roll journaled between said levers, an adjusting lever also fast with said axis, and manually operated means engaging said adjusting lever to alter the position of said takeup roll and thus regulate the length of the path of travel of the web.

3. In a rotary printing press, a web takeup device comprising a fixed guide roll, a pair of lovers fast with the axis of the guide roll, a take-up roll journaled between said levers, an adjusting lever also fast with said axis, and a manually operated screw engaging the end of said ad'usting lever to alter the position of the ta e-up roll and thus regulate the length of the path of travel of the web.

4. In a rotary printing press, a series of printing units, through which the printing web successively asses and a regulating device engaglng sai web etweentheunits, said device comprising a stationary guide roller over which the web passes directly toone of the units, a displaceable roller pivoted on the name to this specification in the presence of axis of the stationary roller and engaging two subscribing witnesses. ihe web in advenice of the lager and means GEORGES CADET or swinging sal p1vote r0 er en lts axis 5 to vary the length of the path of travel of BERNARD OHARLEB LEM DMATTM the web between the printing units, for the Witnesses: purpose described.
